CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rightsapplication number 2017/1945, filed Aug. 9, 2017, which is hereinincorporated by reference.

Latin name of the genus and species: The Latin name of the genus andspecies of the novel variety disclosed herein is Echeveria hybrid.

Variety denomination: The inventive variety of Echeveria hybriddisclosed herein has been given the variety denomination ‘TSAECH1709’.

BACKGROUND OF THE INVENTION

Parentage: ‘TSAECH1709’ is a hybrid seedling selection resulting fromthe controlled pollination of an unnamed Echeveria pulidonis x Echeveriahybrid ‘Perle von Nurnberg’ hybrid plant (not patented), the seedparent, with an unnamed Echeveria lilacina plant (not patented), thepollen parent. The crossing was made by the inventor in the summer of2013 at a commercial greenhouse in Heerhugowaard, the Netherlands. Inthe summer of 2014, one seedling was observed which exhibited uniquegrowth and foliage characteristics. The seedling was isolated forfurther evaluation in order to confirm the distinctness and stability ofthe characteristics first observed. Upon confirmation of distinctnessand stability, ‘TSAECH1709’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar‘TSAECH1709’, by way of rooting leaf cuttings, was first initiated inthe summer of 2015 at the inventor's commercial greenhouse inHeerhugowaard, the Netherlands. Through three subsequent generations,the unique features of this cultivar have proven to be stable and trueto type.

SUMMARY OF THE INVENTION

The cultivar ‘TSAECH1709’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype. The followingtraits have been repeatedly observed and are determined to be the uniquecharacteristics of ‘TSAECH1709’. These characteristics in combinationdistinguish ‘TSAECH1709’ as a new and distinct Echeveria hybridcultivar:

-   -   1. ‘TSAECH1709’ exhibits succulent foliage arranged in a compact        basal rosette; and    -   2. ‘TSAECH1709’ exhibits moderately glaucous foliage; and    -   3. ‘TSAECH1709’ exhibits light greyed-green foliage that is        margined and tipped with pink.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in February of 2018describe averages from a sample set of six specimens of 6 months old‘TSAECH1709’ plants grown in 10 cm nursery containers at commercialgreenhouse in Heerhugowaard, the Netherlands. Plants were produced usingconventional greenhouse production protocols for Echeveria plants whichconsisted of minimal irrigation and fertilizer applications, andchemical pest and disease control measures against mealy bug andBotrytis as required. Plants were grown under approximately 50 percentshade after propagation and later exposed to full sun once they began tomature. No photoperiodic treatments or artificial light was given to theplants.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, with younger plants. ‘TSAECH1709’has not been observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such characteristics are approximations or averagesset forth as accurately as practicable. The phenotype of the variety maydiffer from the descriptions set forth herein with variations inenvironmental, climatic and cultural conditions. Color notations arebased on The Royal Horticultural Society Colour Chart, The RoyalHorticultural Society, London, 2015 (sixth edition).
